Kai's verdictS-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for text-in-image. Use this for posters, Midjourney for art.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
